Comment: Shingled encoding performance penalties (Score 5, Interesting) 219

SMR drives are fine for I/O scenarios that don't overwrite data very often but they suffer from significant performance penalties for overwrites due to the read-modify-write/write-relocate operations required to modify a set of sectors within a shingled-encoded track. There are tricks to lessen the impact such as virtual sector remapping and background remapping but those can't avoid performance penalties in many scenarios.

However that benefit may soon be eclipsed by the gigafactory's impact on roof-top solar power storage costs, putting the entire business model of utilities in peril. “The mortal threat that ever cheaper on-site renewables pose” comes from systems that include storage, said Amory Lovins, co-founder of the Rocky Mountain Institute, a Snowmass, Colorado-based energy consultant. “That is an unregulated product you can buy at Home Depot that leaves the old business model with no place to hide.”"

Comment: Not brave to declare after you've become CEO (Score 1) 764

It doesn't seem all that courageous to me to declare you're gay *after* you've completed the climb up the corporate ladder to the CEO position. It would be more impressive if he did it before the perceived risk to his career had long-since passed. Doesn't set a good example for other gays - hiding the fact you're gay until it's safe career-wise to come out.
